Bethesda announces an announcement within a month

At a New York preview of WET, Bethesda's Pete Hines said that a brand new announcement is "coming in the next month or so" about a game scheduled for a 2010 release. He said that the announcement is not related to Bethesda Game Studios internal projects, nor to any of the iPhone projects. Who knows, maybe they will at last announce some details about Fallout: New Vegas?
